Airtac SAIF Series Standard Cylinder with Valve SAIF100X100S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X100S-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 100mm stroke and a built-in 4M310-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF100X100S-08B
The AirTAC SAIF100X100S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal electrical entry drawing 3.0 W, a PT1/4 valve port, and a -S magnet for CMSE reed or DMSE electronic sensors. The built-in valve provides an effective flow area of 25.0 mm2 (Cv 1.40) and switches at a maximum frequency of 4 cycles per second. Because the manifold routes air via O10 x O6.5 PU tubing directly to the 1/2 cylinder ports, you save panel space and eliminate remote plumbing.
While the bare cylinder body rates to 1.0 MPa, the practical operating pressure for this assembled unit is 0.15-0.8 MPa due to the internal pilot valve limits. In its factory setting, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if the machine logic requires it. Operating at 0.5 MPa, this 100mm bore generates 3927N of push thrust and 3681N of pull thrust, making it suited for heavy-duty positioning.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAIF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAIF datasheet. Port options: PT / G.
Theoretical Output Force (Ø100mm)

| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAIF does not hold its load without air — the valve routes air, it is not a lock. For load-holding use a SAIL (lock) or BSAI (clamp-lock).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF100X100S-08B Is Used
Decentralized Automation
Ideal for large-scale factory lines where routing individual valve lines back to a central manifold is costly. The integrated 4M310 valve lets this 100mm cylinder operate independently from a single DC24V signal.
Heavy-Duty Positioning
Provides 3927N of push force at 0.5 MPa for moving substantial jigs or clamping heavy workpieces directly at the station without requiring external pneumatic amplification.
Machine Retrofitting
Perfect for upgrading existing ISO 15552 fixtures where panel space is tight. The built-in valve and terminal wiring eliminate the need to mount and plumb a separate 5/2 solenoid valve nearby.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X100S-08B the Right Choice?
Choose this 100mm bore when you need substantial push force—3927N at 0.5 MPa—without installing a separate remote valve bank. If your application requires less force, stepping down to an 80mm bore yields 2513N push at 0.5 MPa while reducing air consumption. The self-valved architecture is ideal for decentralized stations across large machines, as a single DC24V wire drives the cylinder, minimizing tubing runs. Remember that the 5/2 valve routes air but does not lock the load; if you need true mechanical holding, consider the SAIL lock variant.
When replacing this unit, verify the 100mm bore, 100mm stroke, PT1/2 cylinder port, and the 4M310-08 valve with DC24V terminal entry. The carbon steel piston rod and -S magnet for CMSE/DMSE sensors are standard. With a 100mm stroke, side loads are minimal, but always ensure proper alignment to maximize seal life.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF100X100S-08B FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder generates 3927N of push force and 3681N of pull force. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) to handle the required air volume.
No separate valve is needed; the unit switches itself. By factory default, the DC24V coil energizes to retract the rod, but you can reposition the valve to extend-when-energised. Note that the 5/2 valve holds position via pilot pressure, not as a mechanical lock.
